Also update Checkstyle to 8.38.
Google changed their style guide from the last time we imported it. This PR brings in those naming changes. The change they made is allowing single letter member, parameter, and local variable names. They also added a lambda naming scheme and I thought it would be good to bring that in too.
This makes code easier to read and more consistent between C++ and Java.
Also update clang-format settings to always add a line break (even if no braces are used).
This adds an overload of UnscentedKalmanFilter::Correct() that takes a
custom measurement covariance but uses default mean and residual
calculation functions.
Closes#2965.
This is a breaking change to the WebSockets layer to align it with
recent specification documentation work.
To support this, HAL SimValue changed readonly to a direction enum.
This allows specifying bidirectional in addition to input and output.
The SimValue change is specifically designed to avoid API and ABI breakage.
This is completely transparent in C++; in Java a new callback class was added,
and the old readonly functions have been marked deprecated.
A new SimValue creation function for enums allows specifying double values
for each enum value, not just strings. This allows mapping enum values to
doubles in the WebSockets layer.
A ":" in the SimDevice name now maps it to different WebSocket types (e.g.
"Accel:Name" becomes type "Accel", device "Name"). The type is hidden
in the GUI.
Other WebSockets changes:
* Implemented match_time and game_data
* Added joystick rumble data
* Added builtin accelerometer support
* SimValue enums are mapped to string and double value on WS interface
* Added WebSockets protocol specification
* Added READMEs
If the strncpy() bound is equal to the destination size and the source
string is longer than 256 bytes, strncpy() won't write a null terminator
for the destination string.
This allows joystick testing without a physical joystick.
Comes with a default set of keyboard mappings, but these are fully customizable by the user.
Up to 4 virtual joysticks are supported.
Default keyboard mappings:
Joystick 0: axis 0: AD, axis 1: WS, axis 2: ER, buttons ZXCV, POV on numeric keypad
Joystick 1: axis 0: JL, axis 1: IK, buttons M,./
Joystick 2: axis 0: left/right arrow, axis 1: up/down arrow, buttons insert/home/pgup/del/end/pgdn
Also adds support for DS-style hotkeys of []\ enable, Enter disable, and spacebar disable.
All of these are disabled by default and must be explicitly enabled by the user.
Currently, Encoder.reset() must make a round trip to the sensor and back
in order for the count to be updated for the user program. As the sim layer
also resets the internal encoder count, this creates a race condition (a WS
message with a new count can be "in flight" during a reset and update the
count).
This changes the WS layer to not put reset on the wire, but instead keep an
offset count internal to the robot program. The value on the wire is not
reset, but rather all sends and receives are adjusted as necessary to the
internal robot count.
This approach is straightforward, but does result in the value on the wire
not matching the value in the user program. A future improvement will fix
this, but this change fixes the immediate race condition problem.
